order to achieve an environmental outcome equal or better than the wetland values that are impacted.
Refer to section 81A of the Environmental Protection Regulation 2008 for the list of wetland values.

Where a wetland management area is mapped as being of ‘high ecological significance under the
Queensland Coastal Plan it should be assessed against State Planning Policy 3/11:Coastal Protection
(SPP3/11). Refer to policy 3 Nature Conservation in SPP 3/11.

¢ Maintain wetland water quality. The water quality of any waters in and linked to the wetland is
maintained and managed to protect the environmental values of the wetland, and to ensure that the
water quality objectives listed under Schedule 1 of the Environmental Protection (Water) Policy 2009 are
achieved.

e Maintain wetiand water regime. The existing water regime (including surface and groundwater) within
and linked to the wetland is maintained and managed to protect existing natural hydrological processes
within the wetland ecosystem. This includes safeguarding natural fluctuations in size and location of the
wetland, and retaining and allowing for regeneration of native vegetation.

To ensure that the proposed development is able to meet the above outcomes, the assessment
manager is encouraged to consider the requirement for a buffer area between any proposed works and
the wetland. A wetland buffer has two components:

¢ asupport area adjacent to the wetland that maintains and supports the environmental values of the
wetland; and

e® aseparation area around the support area that protects the wetland from external threats such as
sediment and nutrient discharge from surrounding landuse.

Buffer distances should be maximised in order to maintain existing biodiversity values, habitat
connectivity and to minimise edge effects. Unless otherwise determined by a suitably qualified
professional, the following buffer widths are accepted by EHP as precautionary buffer widths likely fo
absorb impacts from external uses.

e within urban areas, a minimum 50m buffer to wetland
e outside of urban areas a minimum 200m buffer to wetland

Note: The Queensland Wetland Buffer Planning Guideline (2011) should be referred to when planning
detailed buffer design to position development, determine any alternative buffer widths and establish
operating measures that avoid adverse impacts on a wetland,

Where required, revegetation of the buffer is recommended using native species representative of the pre-
clearing regional ecosystem, with preference given to endemic species. Plants should be of local
provenance where possible. A rehabilitation’ revegetation management plan including weed management
strategies may assist in determining the rehabilitiation requirements for the development. Conditioning of any
approval with building or development envelope(s) may also be a useful way to give formal effect to any
required buffer area.

The assessment manager should consider requiring applicants to provide a Stormwater Management Plan
to demonstrate how stormwater, sediment and other run-off from the site (associated with the construction
and operational phases of development) will be effectively managed to prevent adverse impacts on wetland
values. Potential impacts are to be addressed through water sensitive urban design including compliance
with South East Queensland Regional Plan 2009-2031 Implementation Guideline No. 7: Water sensitive
urban design - design objectives for urban stormwater management. For areas outside of the South-east
